# 实现peek函数:Java基础教程 在数据结构中,peek函数是一个常用的操作,特别是在栈(Stack)和队列(Queue)中。它用于查看当前的数据,但不移除该数据。本文将为一位刚入行的小白开发者提供详细的步骤和代码示例,帮助他实现peek函数。 ## 实现peek函数的流程 我们将通过以下步骤实现peek函数: | 步骤 | 描述 ...
Stack.peek（）和Stack.pop（）的区别 Stack.peek（）和Stack.pop（）的区别Stack.peek()peek()函数返回栈顶的元素，但不弹出该栈顶元素。Stack.pop()pop()函数返回栈顶的元素，并且将该栈顶元素出栈。
Built-in Function:void *__builtin_return_address(unsigned intlevel) This function returns the return address of the current function, or of one of its callers. The level argument is number of frames to scan up the call stack. A value of0yields the return address of the current function,...
